Ains

AINS is an acronym used in multiple contexts, and there is no single universally accepted expansion. Its meaning depends on the domain and region, with medicine being one of the more widely encountered usages in certain languages.

In pharmacology, particularly in Francophone literature, AINS stands for anti-inflammatoires non stéroïdiens, the class known in English as nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs provide analgesic, antipyretic, and anti-inflammatory effects by inhibiting the cyclooxygenase enzymes COX-1 and COX-2, which reduces prostaglandin synthesis. Common agents include ibuprofen, naproxen, diclofenac, and acetylsalicylic acid. They are used to relieve pain, reduce fever, and treat inflammatory conditions, but can cause adverse effects such as gastrointestinal irritation, ulcers, kidney impairment, and cardiovascular risks, especially with long-term use. Guidelines emphasize using the lowest effective dose for the shortest duration and considering contraindications such as NSAID allergy, active peptic ulcers, or certain kidney or liver conditions.

Outside of this medical usage, AINS may denote various organizations, systems, or terms that differ by country and field. Because there is no standard expansion, the intended meaning of AINS is usually clarified by the surrounding text or by a full form provided within a specific document or discussion. In ambiguous cases, readers should seek additional context to identify the correct interpretation.
